Organic acid - carbon chemical compound with other elements. They are permanent components of the plant, along with carbohydrates and proteins, sometimes exceeding the content of the latter. They define taste plants and sometimes smell. They are in form of solutions in cell sap of many plants in free form or in salt form. Plants contain organic fatty acids and aromatic, which have a cyclic structure. Organic fatty acids are very diverse. The most common are malic, citric, acetic, oxalic. There is a lot of citric acid in the lemon (up to 9% of the dry weight) in the leaves of tobacco (7.8%), cotton, and in garnets, cranberries, etc. Malic acid is found in significant numbers in the fruits of mountain ash, barberry, and dogwood in apples. A lot of oxalic acid is in sorrel (10-16%), spinach, begonias.

Carbohydrates - a large group of natural organic compounds consisting of carbon, oxygen and water. There are mono-, oligo-and polysaccharides, as well as complex carbohydrates - glycoproteins, glycolipids, glycosides, etc. The plants are the primary products of photosynthesis and the main source products of biosynthesis of other substances that are included in the composition of cell membranes and other structures, involved in the defense response (immunity) provide all the energy of living cells (fructose, glucose and its replacement form - starch, glycogen). Using sunlight by photosynthesis, green plants combine carbon dioxide of air and water, and receive sugar, or as they are known, carbohydrates, and moreover, release oxygen.

Pectin (from the Greek. Pectos - thickened, coagulated) - are part of the cell-cell adhesive substance. This is close to the gums and mucous carbohydrate polymers, consisting of a uronic of acid residue and monosaccharides. Are polysaccharides of the cell walls. The main component of pectin polysaccharides are polyuronic acid. Small part in the pectin polysaccharides are neutral - arabinans and galactans.

Life, according to generally accepted definition of Engels is a special form of existence of proteins, which are based on the exchange of matter and energy. Every organism, every living cell is composed of proteins - large polymer molecules are very complex and unique, typical for almost every organism.Proteins are synthesized in cells by the so-called genetic code in special molecular matrices - complex molecules of DNA and RNA, and therefore differ in precise individuality. Each cell has different types of proteins. Some of them form the outer semipermeable membrane, the so-called lectins. They strictly control in order a substance, a virus or disease-causing germs are not penetrated into the cell,. From them, as some believing depends cessation of cell division, and when they do not perform their functions, cells continue to chaotic, randomly devide themselves - and a tumor are formed. Other proteins form a double membrane, which forms a new cell organelles, and others are in stock, etc.

To stabilize protective forces of organism is needed the whole set of necessary micronutrients.The main micronutrients: iron, iodine, cadmium, cobalt, silicon, lithium, manganese, copper, molybdenum, selenium, sulfur, strontium, fluoride, chromium, zinc. Essential micronutrients that stimulate hematopoiesis, are iron and copper. Their lack does not only reduce resistance to disease, but also leads to mental retardation, stunted growth, disruption of vascular elasticity. Trace elements and their complexes in plants usually do not cause toxic side effects even when excess.
